Together with the VistaPlus Digital amplifier, the Plantronics SupraPlus Digital headsets set truly new standards in audio performance whilst meeting Health & Safety requirements that, by their nature, limit the audio performance of headset systems. Memory on board the SupraPlus Digital headset allows the VistaPlus to tune the system performance to optimize to the limits of Health & Safety requirements. Up to 12dB louder than standard headsets, the SupraPlus Digital headset enables higher accuracy & less fatigue in the Contact Centre. Designed for all-day wearing comfort, SupraPlus Digital is available in monaural or binaural versions, and offers either a voice tube or noise-cancelling microphone.
